The bus was running in downtown in the first day of the official visit of US President Barack Obama to Belgium.

According to local police, the traffic in the capital’s downtown has been restored.

The incident occurred amid unprecedented security measures regarding the start of the official visit of US President Barack Obama to Belgium. Obama has arrived overnight to Wednesday. However, he is not in Brussels now: the US president is in Flemish town of Waregem, where is taking place a solemn ceremony at a military cemetery near the graves of US soldiers that were killed in World War I (1914-1918).
